CONTAINER CLOSURE Filed May 8, 1950' l atented Jan. 12, 1932 ITED STATES WILLIAM H. ROSE, OF JERSEY CITY, NEW JERSEY CONTAINER CLOSURE Application filed May 8,1930. Serial No. 450,865.

My invention relates to container closures and refers particularly to closures adapted for use with readily penetratable containers.

The object of my invention is a container closure, preferably of metal, capable of adaption as a closing means for containers composed of penetrata-ble material, such as paper, cardboard, fibrous materials and similar substances.

A closure of this character should be economic in production, readily applied, capable of removal and replacement without injuring the container walls, and capable of producing an air-tight and liquid tight seal between the closure and the container.

The container closure of my invention which possesses all of the above-mentioned, and other, valuable features comprises an anchor, or anchoring member capable of attachment to the outer wall of a container without causing leaking at the points of attachment, and a closure member capable of placement over the open end of the container and capable of attachment to the anchor, thus forming a seal between the closure member and the wall of the container.

My device also possesses the great practical value that it can be readily removed to gain access to the contents of the container and replaced in sealed position without injury to the container.

The many advantages of my device will be evident upon a consideration of my specification and drawings explaining several modifications of my device, but I do not limit myself to the particular modified forms thus explained and shown. I

In the accompanying drawings illustrating modified forms of the device of my invention similar parts are designated by similar numerals.

Figure 6 is a fragmentary vertical section of a modified form of the device of my invention.

Figure 7 is a fragm'entaryvertical section of a modified form of the device of my invention.

Figure 8 is a perspective view of one form of an anchor of the device of my invention.

Figure 9 is a fragmentary plan view show ing one form of end attachment of one form of anchor.

' Figure 10 is a fragmentary plan view showing a modified form of end attachment of one form of anchor.

Figure 11 is a perspective view of the anchor shown in Figures 4. and 6.

Figure 12 is a perspective view of the anchor shown in Figure 8, with the rib extending across the top thereof.

The particular form of my device shown in Figures 1 and 8 of the accompanying drawings comprises an annular anchoring member having the central continuous rib 20, and a plurality of right angled positioned prongs 21, 21, said prongs being inserted into the side 22 of an annular container. The closure member consists .of the central cover 23, which is extended into the channelshaped flange 24 and a plurality of downwardly extended prongs 25, 25, the extremity of each prong extending downwardly beyond the anchor member and capable of being bent thereunder.

"In operation, the anchoring member is placed around the exterior face of the container, the teeth 21, 21, being inserted into the side 22 of the container. A soft, or resilient, washer 26 is placed upon the upper face of the wall 22, the closure member placed upon the container with the wall 22 positioned within the channel-shaped flange 24;. The cover is then pressed downwardly and the prongs 25, 25 bent inwardly beneath the anchoring mem er, thus causing the cover to maintained firmly in place and causing he In w oil the anchoring member is inclined with respect to the bent portions of the anchor prongs 21, 21 and hence IS in a plane at angles to that of the container wall 22. in

the closure of this modification the free end of each prong 25 has an inwardly bent fastenmember 27.

ln operation, the anchor is positioned as shown and the closure member is forced downwardly, each fastening memher being bent slightly outwardly by the anchoring member, the resilience of the prong causing the fastening member to move beneath the anchoring member to maintain the closure in position.

In the modified form shown in Figure 3, the series of prongs 28 is positioned at an acute angle to the "lb 20, while the series of prongs 29 is positioned at right angles thereto. The closure comprises the cover 30 having the channel-shaped flange 31, which is extended outwardly 32, and downwardly 33 and has a plurality of prongs 34; capable of being bent under the anchor.

In the modified form shown in Figure l, the anchor comprises the rib 35 and a plu rality of prongs 36 which are bent inwardly 37, outwardly 38 and inwardly 89. The closure comprises the cover 40 having the chan- Incl-shaped flange e1 which is extended outwardly 42, then downwardly 48, and carries a plurality of prongs the end is of each being capable of being bent beneath the anchor.

In the modified form shown in Figure 5, the anchor comprises the rib 45, having a series of prongs 4:6 bent angularly as l? and then inwardly as 48, and a second series of prongs l9 bent inwardly at right angles as 50, then outwardly as 51 and then inwardly as 52. lhe closure comprises the cover 53 having the channel-shaped flange 5a, the lower peripheral portion of which is turned inwardlyto form the member 55 capable of placement beneath the anchor.

In the modification shown in Figure 6 the anchor is similar to, that shown in Figure l except that the lower series of prongs is positioned angularly to those of the upper series, and the closure is similar to that shown in Figure l. I

In order to give increased stability to that portion of the anchor extending beyond the container wall 22, if desired, a strip of paper, felt or other suitable material may be placed within the anchor. This strip may be applied to any of the forms of anchors shown, or suitable for my purpose, and in Figure 7,

I show this strip 56 adapted to an anchor comprising a rib 57, having two series of prongs 58 each being bent outwardly as 59 and inwardly as The two ends anchor may be fastened lass tos't'ier after placement aroun tainer wall 22, spotwelding til, 3 iown in igure 9, or a pro ecting ton o2 of o.- c

exception or". that of Figures 2 and 5, closure is attached to the anchor by bending its prongs beneath the anchor, while in the modification of Figures 2 and 5, the closure is pressed downwardly the prong 27 of Figure 2 and the prong 55 of Figure 5 springing into place beneath the anchor.

The anchor need not be a continuous one extending around the wall of the container, as similar results can be obtained by a plurality of separate anchors properly positioned to receive the prongs of the closure.

order to obtain access to the interior of the container, the closure prongs are bent outwardlyt'rom contact with the anchor and the closureremoved without injuring the container. The closure can thus be readily replaced into closed position.

It will thus be seen that in the device of my invention an anchor having extended prongs is attached to the walls of a container b inserting said prongs within said wall allowing a portion of said anchor to extend beyond said wall, and that the closure is attached to said anchor by means of prongs, or extended members carried by said closure and positioned beneath said anchor.

lit will be further noted that the closure may be readily removed without injury to the Walls of the container and can be replaced and fastened into closed position.

I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described as these are given simply as a means for clearly describing the device of my invention.
